Specification of Letters Patent.

Application filed. June 18, 1909.

Patented Jan. 3, 1911.

Serial No. 502,948.

To all whom it may concern:

Be it known that I, THOMAS WV. HUTCHIN- SON, a citizen of the United States, residing at Middlebury, in the county of Elkhart, State of Indiana, have invented certain new and useful Improvements in Tire-Bolt renches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wheel-wright tools and more particularly to the kind employed in tightening on tire bolts.

It has for its object the provision of a device of that kind which may be readily adjusted to the various thicknesses of fellles.

Another object is the provision of a device for engaging the Wheel and holding the same against movement during the operation of tightening the nut and bolt.

A further object is the provision of a con struction for engaging the bolt during the tightening of the nut so as to prevent the bolt from turning.

IVith these and other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of the specification:Figure .1 is a side elevation of the device showing its application to a wheel and in position to tighten the tire bolt. Fig. 2is asimilar view but showing the position of the parts after the wheel has been removed. Fig. 3 is a longitudinal sectional view of the device. Fig. 4 is a plan view. Fig. 5 is a sectional end elevation taken on the line 5-5 of Fig. 4:. Fig. 6 is a bottom plan view of the device.

Similar numerals of reference are employed to designate corresponding parts throughout.

In the drawings, the numeral 5 represents the felly of the wheel, 6 the spokes, 7 the nut and 8 the bolt which extends through the felly and tire 9. In order that the nut may be tightened on to the bolt after the tire has been placed on the rim or in order that the nut may be removed whenever desired it is obvious that a wrench or the like must be employed to engage the nut. The present invention aims to provide such a device and in the present instance is shown to consist of a bracket arm 10 which maybe of any suitable length and is preferably formed of a single piece of metal, oblong in contour and having a portion adjacent one end turned at right-angles as shown at 11. The opposite sides of the body portion 10 of the bracket may be beveled for a purpose to be presently described. That end of the bracket arm remote from the right-angular extension 11 is provided with openings for the reception of bolts 12, or the like by means of which it is secured to a bench or table 13 in such position that the opposite or angular end will project considerably in advance of the side or end of the table to which the op posite end is secured. What will subsequently be termed a wrench carriage is in the present instance shown to consist of a rectangular shaped housing having opposite side walls 1 1 and 15 which are connected by means of the front and rear walls 16 and 17. The lower end portions of the side walls 14 and 15 extend a trifle below the lower end of the front and rear walls 16 and 17 and are spaced apart sufficiently far to completely straddle the body portion 10 of the bracket and are inclined slightly outward to conform to the beveled sides of the body portion 10 and are thence turned inwardly as shown at 18 so as to bear on the lower face of the body portion 10 of the bracket. Thus it will be seen by virtue of the disposition of the parts the carriage will be slidingly fitted on the portion 10 of the bracket, the lower edges of the front and rear walls bearing on that face of the bracket opposite to the in-t-urned portions 18. The upper ends of the side, front and rear walls are connected by the top 19. The carriage may be of any suitable height and in the present instance is shown to be slightly greater than the height of the right-angular extension 11 at the free end of the body portion 10. J ournaled in the front and rear walls 16 and 17 are the opposite ends of a shaft 21. This shaft is disposed adjacent the top or cover 19 and has keyed thereto and disposed within the carriage and adjacent the rear wall 17 a crown gear 22. That end of the shaft extending through the front wall16 1s provided with a bore which is non-cylindrical in contour and is designed to receive the a crank handle 25. That portion of the shaft 24: disposed within the carriage has angular extension 11 is one end of a lever 33 which moves in a horizontal plane, and projecting from the central portion and adjacent the lower end of the front wall 16 drawn into engagement with the nut to be turned, and after the latter has been tight- 5. shank of a socket 23. The latter may be of of the carriage is a right-angular shaped any well known type and is of a size to fit hook 34 and connection between the hook the nut to which it is to be applied. By 34 and that portion of the lever adjacent 1ts virtue of the bore at the front end of the pivotal point is established by means of a shaft 21 sockets of various diameters may be link 35, one end of which is provided with 10 readily inserted therein, according to the an opening to receive the hook 34 and the opnut to be turned. The front and rear walls posite end of which is pivoted to the lever.

7 16 and 17 are provided with openings dis- Thus it will be seen when the lever is moved posed beneath the openings for the reception in one direction it will carry with it the link of-the shaft 21 and lying in a vertical plane 35, and by virtue of the latters connection 15 with the latter and these openings are in diwith the carriage the latter will be moved 8 rect alinement with the openings formed in toward the right-angular extension 11, and the right-angular extension 11. Journaled as the carriage moves the shaft 24- will likein these openings is a shaft 2 1, one end of wise move through the openings in the rightwhich extends considerably in advance of the angular extension 11. This will be the posi- 2 extension 11 and is provided at one end with tion of the parts when the socket has been J'keyed thereto a crown gear 26, the teeth of which mesh with the gear 22. Thus it will 25 be seen when the crank handle is turned the socket 23, through the gears 22 and 26, will be rotated.

ened or disengaged from the bolt, by moving the lever in the o posite direction the socket will be moved sufllciently far from the wheel in order that the latter may be turned so as ruin By referring now to Fig. 1 it will be seen that the socket 23 is in position to turn the to bring the next nut into position to be engaged by the socket.

Having thus described my invention what 30 nut and in order to prevent the bolt from is claimed as new, is turning with the nut as the socket rotates r 1. A tire bolt wrench comprising a horiaclamp screw 27 is employed. This member zontally disposed arm having its opposite is threaded through an opening adjacent the longitudinal sides beveled and terminating upper end of the right-angular extension 11 at one end in a vertical extension, a carriage 35 and in axial alinement withthe' socket 23, having portions adjacent the lower ends of the outer end of the clamp screw 27 being its opposite sides beveled and bearing on the provided with a hand wheel 28. Thus it will beveled sides of the arm and further probe seen when the wheel has been secured in vided on its opposite sides and below the place as shown in Fig. l and the socket beveled portions with in-turned extensions 40 brought to engage with the nut, by turning bearing on the lower face of said arm, a the clamp screw 27 its inner end will bear on socket rotatably mounted in said carriage, a the end of the bolt sufiiciently to prevent the shaft journaled in said carriage and in said latter from turning as the nut rotates with vertical extension and adapted to rotate said the socket. Vhen the parts are in this posisocket, a clamp screw threaded into the ver- 5 tion and it is undesirable to have the wheels tical extension and in axial alinement with move a fork 29 is provided. This member said socket, an operating lever havin one is'provided at its lower end with jaws 30, end pivoted to said arm in advance of said "which straddle the upper end of the rightcarriage and operating to advance said carangular extension 11 and are secured thereto riage in the direction of said clamp and a 50 by means of a pivot bolt 31. The jaws conlink connection between said operating lever verge into a shank, which likewise termiand said carriage, said link overlying said nates in bifurcations 32 which are curved arm and being terminally connected to the to substantially a U shape. The fork 29 is lever in approximately the plane of said so disposed that it will move to and from the socket, whereby wabbling of the carriage carriage so that when a wheel has been sewhen being advanced on the arm is precured in place as shown in Fig. 1, the former vented. may be lowered so as to engage the spokes 2.
